— MacNJeesus on Reddit

“It was well worth the money and time to install.”
— dreamerdreamings on Reddit

“I have Viofo A129 Plus Duo and while I’m very happy with the recording quality, the app simply does not work and the OEM hardwire harness kit (which is the only brand that works with this camera) has horrible quality and will die on you within a year. For those reasons I’d recommend staying away from viofo.”
